Matrix norm - Wikipedia

WebThis norm is also called the 2-norm, vector magnitude, or Euclidean length. n = norm (v,p) returns the generalized vector p -norm. n = norm (X) returns the 2-norm or maximum singular value of matrix X , which is approximately max (svd (X)). n = norm (X,p) returns the p -norm of matrix X, where p is 1, 2, or Inf: If p = 1, then n is the maximum ... Web12 de ago. de 2015 · Norms ("just" a norm): Sometimes a norm is just a norm. Often, it's useful to think of a matrix as "a box of numbers" in the same way that you would think of a vector in $\Bbb R^n$ as a "list of numbers". A "matrix norm" by this definition is any function on the matrices that satisfies the usual rules that define a norm. Web24 de mar. de 2024 · Spectral Norm. The natural norm induced by the L2-norm.
